RAID 01 is also called as RAID 0+1
Main difference between RAID 10 vs RAID 01
[*]Performance on both RAID 10 and RAID 01 will be the same.[*]The storage capacity on these will be the same.[*]The main difference is the fault tolerance level. On most implememntations of RAID controllers, RAID 01 fault tolerance is less. On RAID 01, since we have only two groups of RAID 0, if two drives (one in each group) fails, the entire RAID 01 will fail. In the above RAID 01 diagram, if Disk 1 and Disk 4 fails, both the groups will be down. So, the whole RAID 01 will fail.[*]RAID 10 fault tolerance is more. On RAID 10, since there are many groups (as the individual group is only two disks), even if three disks fails (one in each group), the RAID 10 is still functional. In the above RAID 10 example, even if Disk 1, Disk 3, Disk 5 fails, the RAID 10 will still be functional.[*]So, given a choice between RAID 10 and RAID 01, always choose RAID 10.
**** I am not from asrock. So if you want to Wait for someone who has this board might be a good idea.
I can say that the manual, has a lot of general items and sometimes its from a bunch of different boards, my manual for my X79 is a joke.
